Medical diagnosis is the way toward figuring out which illness or condition clarifies a man's side effects and signs. It is frequently alluded to as analysis with the medicinal setting being verifiable. The data required for conclusion is normally gathered from a history and physical examination of the individual looking for therapeutic agents. Frequently, at least one indicative methodology, for example, analytic tests, are additionally done amid the procedure. In some cases, posthumous finding is viewed as a sort of medicinal analysis. Finding is frequently testing, because many signs and side effects are nonspecific. For instance, redness of the skin systematic lupus erythematous without anyone else's input is an indication of many issue and in this manner, doesn't tell the human services proficient what isn't right. In this manner differential analysis, in which a few conceivable clarifications are considered, must be performed.

Nuclear Medicine includes the field of Molecular imaging. It uses in very small amounts of radioactive materials (radio pharmaceuticals) to diagnose and treat disease. In nuclear medicine imaging, the radio pharmaceuticals are detected by special types of cameras that work with computers to provide very precise pictures of the area of the body being imaged.
